Not Every Spirit explores the notion of Christian faith as disbelief and how the task of "testing the spirits" develops and comes to be understood within Christianity as a theological discipline called dogmatics. It also focuses on uncovering disbeliefs of the Christian faith concerning the Word of God, the being of God, Jesus Christ, the Holy Spirit, creation, salvation, humanity, the church, and the life to come. This book is a fresh and timely dogmatic text that will take its place as a standard work on Christian teachings.
